如何在Rust中使用Tera创建数组？

use tera::Tera;

let tera = Tera::new("templates/**/*.html")?;

let context = tera::Context::new();
let rendered = tera.render("template.html", &context)?;

let mut context = tera::Context::new();
context.insert("array", &vec![1, 2, 3]);

use tera::Tera;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let tera = Tera::new("templates/**/*.html")?;

    let mut context = tera::Context::new();
    context.insert("array", &vec![1, 2, 3]);

    let rendered = tera.render("template.html", &context)?;
    println!("{}", rendered);

    Ok(())
}
